🧠 DSA-Java Notes & Practice
This repository contains my Data Structures & Algorithms (DSA) practice notes and examples using Java. It’s designed to help me strengthen my problem-solving skills and learn how to implement common data structures and algorithms in Java.
Every file includes well-commented explanations that make the logic easy to understand and practice.
🎯 What’s Included
This repository focuses on core DSA topics implemented in Java:
✔ Arrays & Linked Lists ✔ Stacks & Queues ✔ Trees & Binary Trees ✔ Graphs (basic exploration) ✔ Searching & Sorting Algorithms ✔ Recursion techniques ✔ Hashing & Hash Tables ✔ Time/Space complexity notes ✔ Practice problems & solutions
📂 Project Structure DSA-Java-Notes/ │ ├── [Java files] # Algorithms & data structure implementations ├── README.md # Project overview
Each .java file contains examples, logic, and comments so you can read, practice, and modify the code to learn DSA effectively.
🛠️ Running the Code
To compile and run any Java file:
Compile:
javac FileName.java
Run:
java FileName
Alternatively, you can use any Java IDE like:
IntelliJ IDEA
Eclipse
NetBeans
VS Code (with Java extensions)
📈 What You’ll Learn
By working with this repository, you will:
✔ Understand key DSA concepts with Java ✔ Build logic to solve programming problems ✔ Learn how to implement data structures from scratch ✔ Improve problem-solving & coding strength ✔ Prepare for interviews and competitive coding
⭐ Future Improvements
I plan to add:
✨ More advanced algorithms (Dynamic Programming) ✨ Graph algorithms (BFS, DFS, Dijkstra, etc.) ✨ Example problems from coding platforms ✨ Explanations with time/space complexity ✨ Test cases for each implementation
